Abstract

Protected areas may function as islands of habitat in otherwise adverse environments for many species of North American animals. It is currently unclear how to maintain suitable foraging habitat for bats within these areas. Bats are nocturnal and highly mobile, making their specific needs difficult to determine. Using data collected from acoustically surveyed sites within protected areas in the Oak Openings Region of Northwest Ohio, a biodiversity hotspot, we developed spatially explicit macrohabitat models using maximum entropy modeling (Maxent). We then used data collected by citizen scientists to test these models to determine their success in predicting species presence. We found that the models were successful (AUC values > 0.75) at predicting the occurrence of the seven species for which models were developed, Lasionycteris noctivagans, Lasiurus borealis, Lasiuruscinereus, Myotis lucifugus, Myotiss eptentrionalis, Nycticeius humeralis, and Perimyotis subflavus.  Within protected areas, it is important to manage for heterogeneous habitat composition at this intermediate scale to maintain potential for foraging areas for all occurring bat species. Data collected by citizen scientists is useful to test spatially explicit models and can potentially be used to monitor long term changes in bat species composition in these systems and across regions. Key words: Bats, maxent, northwest Ohio, citizen science, parklands.

Highlights

  • Studies on the activity of bats in the summer are often based in areas that are relatively forested and intact (Brigham, 2007)

  • Our goals were to develop a macrohabitat model of bat presence for all occurring bat species at the macrohabitat level using Maxent, and demonstrate the usefulness of testing these models with data collected from citizen scientists

  • For seven bat species that occur within the Oak Openings Region of Northwest Ohio, we successfully developed a macrohabitat model that predicted presence in the protected areas and increased our understanding of critical habitat components

Summary

Introduction

Studies on the activity of bats in the summer are often based in areas that are relatively forested and intact (Brigham, 2007). How bats utilize protected areas is unclear, but studies have demonstrated higher species diversity inside parks compared to outside of them (Avila-Flores and Fenton, 2005; Duchamp and Swihart, 2008; Glendell and Vaughn, 2002; Jung and Kalko, 2011). This suggests that protected areas may serve as a critical refuge from human-mediated impacts
